The multi-system of electro-phytotechnology using a woody ornamental cadmium (Cd) hyperaccumulator ( Thunb.) is a new departure for environmental remediation. The effects of four electric field conditions on Cd accumulation, growth, and photosynthesis of under four Cd treatments were investigated. Under 25 and 50 mg L Cd treatments, Cd accumulation in was enhanced significantly compared to the control and reached 1110.79 mg kg in root and 428.67 mg kg in shoots influenced by the electric field, especially at 2 V cm, and with higher bioaccumulation coefficient (BC), translocation factor (TF), removal efficiency (RE), and the maximum Cd uptake, indicating that 2 V cm voltage may be the most suitable electric field for consolidating Cd-hyperaccumulator ability. It is accompanied by increased root and shoots biomass and photosynthetic parameters through the electric field effect. These results show that a suitable electric field may improve the growth, hyperaccumulation, and photosynthetic ability of Meanwhile, low Cd supply (5 mg L) and medium voltage (2 V cm) improved plant growth and photosynthetic capacity, conducive to the practical application to a plant facing low concentration Cd contamination in the real environment.
利用木本观赏镉（Cd）超积累植物（ ）的电植物技术多系统是环境修复的新起点。研究了四种电场条件对四种镉处理下 镉积累、生长和光合作用的影响。在25和50 mg L镉处理下，与对照相比， 中的镉积累显著增强，在电场影响下，根部镉积累达到1110.79 mg kg，地上部达到428.67 mg kg，特别是在2 V cm时，生物积累系数（BC）、转运系数（TF）、去除效率（RE）和最大镉吸收量更高，表明2 V cm电压可能是巩固镉超积累植物能力的最合适电场。通过电场效应，它伴随着根和地上部生物量以及光合参数的增加。这些结果表明，合适的电场可能会提高 的生长、超积累和光合能力。同时，低镉供应（5 mg L）和中电压（2 V cm）改善了植物生长和光合能力，有利于在实际环境中对面临低浓度镉污染的植物进行实际应用。
